Each 36 of these subnodes represents muxing for a pin, a group, or a list of pins or 37 groups. 38 39 The name of each subnode is not important; all subnodes should be enumerated 40 and processed purely based on their content. 41 42 Required subnode-properties: 43 - st,pins : An array of strings. Each string contains the name of a pin or 44 group. 45 - st,function: A string containing the name of the function to mux to the pin or 46 group. See the SPEAr's TRM to determine which are valid for each pin or group. 47 48 Valid values for group and function names can be found from looking at the 49 group and function arrays in driver files: 50 drivers/pinctrl/spear/pinctrl-spear3*0.c 51 52 Valid values for group names are: 53 For All SPEAr3xx machines: 54 "firda_grp", "i2c0_grp", "ssp_cs_grp", "ssp0_grp", "mii0_grp", 55 "gpio0_pin0_grp",
